A ll the fancy stuff was gone Sunday, and the Warriors were down to just guts and stubborn adrenaline.

Which is usually not nearly enough to beat the San Antonio Spurs when the Spurs are lining up a playoff kill-shot.

Who are the Warriors if Stephen Curry is badly limited, their shots aren”t falling, they”re in foul trouble and losing Game 4 at Oracle Arena?

We found out. More important: The Warriors found out, too.

They still might not win this series, but they absolutely dug something out of themselves Sunday.

“Your backs are against the wall, you”re at home, you”re playing like crap in the first half, you”re down,” center Andrew Bogut said.

“Then you come back and you fight it out.”

Oh, yes the Warriors did. They scrapped, they scrambled, they played madman defense, they leaned on Harrison Barnes, and they even played Andris Biedrins.

And what happened? The Warriors patched it together, stormed back in the fourth quarter, then rallied past the Spurs in overtime 97-87 to tie the series 2-2, which now heads to San Antonio for Game 5 on Tuesday.

Of course they did.

“One thing I know, this team will not lay down,” Warriors coach Mark Jackson said. “This team will not quit.

“It looked dark. It looked awfully dark. But we found a way to get stops and to make plays.”

Somehow, they did it with Curry limping on a sprained left ankle that reduced him to essentially standing in a spot and waiting for the ball to come to him.

He still managed to score 22 points on 7-for-15 shooting in 39 grueling minutes, but he said later that he almost didn”t play—and needed an anti-inflammatory shot Sunday to get through it.

“He said, ”I”m going to give you what I”ve got, Coach,”” Jackson said of his pregame talk with Curry. “That”s not the language he speaks. I knew right away that he was not 100 percent.”

But it was enough. For this game, Curry watched other Warriors carry the larger load.

And how will Curry be for the rest of this series?

“As long as we can get to San Antonio in the same shape as I am right now, it should be good,” said Curry, who has taken three injections in the postseason.

No, this was not the perfect Warriors playoff formula, and in fact it was the opposite happening, all at once, all wildly imperfect.

In a do-or-die game for the Warriors, it couldn”t get any clunkier, any more desperate, anything further from the way the Warriors have won in these playoffs or this season.

Who were the saviors Sunday? Not the usual guys, that”s for sure. How”d they do it? Not anything close to the usual way.

Biedrins gave them three big minutes in the second quarter; Richard Jefferson played five crucial minutes; David Lee made it through eight minutes only a few weeks after his hip-flexor tear.

And Jarrett Jack, Bogut and Barnes all playing starring roles.

“You look at a guy like Biedrins, called upon, gave us great minutes,” Jackson said. “I mean, we”ve got an incredible group.

“People beat up Jarrett Jack. ”Why is he pounding the ball? Bench him.”

“I”m going to go with this group until I”m not here. This is a great group, and I”m committed to them, they”re committed to me.”

If the Warriors can beat the Spurs when Curry is a secondary player, when the Warriors shoot only 38 percent, and when they trailed by double digits several times …

Well, then the Warriors can win almost anywhere, anytime, with whomever Jackson puts out there.

The Warriors are in this fight, and they aren”t ready to get knocked out — not here, not in San Antonio, not anywhere.

“It”s a grind, man,” Curry said. “It”s almost like we played better there and they played better here. So I don”t know what to read into that.”

All the Warriors know is that they are swinging away, not always at full strength, and it doesn”t matter, as long as they have their guts and their adrenaline.
